docker搭建nginx实现负载均衡
docker搭建nginx实现负载均衡
安装nginx
查询安装
[root@localhost ~]# docker search nginx
[root@localhost ~]# docker pull nginx
准备
创建一个空的nginx文件夹里面在创建一个nginx.conf文件和conf.d文件夹
运行映射之前创建的文件夹
端口:8075映射80
docker run -it \
--name nginx \
-p 8075:80 \
-p 8080:8080 \
--privileged \
--network wn_docker_net \
--ip 172.18.12.90 \
-v /etc/localtime:/etc/localtime \
-v /usr/local/software/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v /usr/local/software/nginx/html:/usr/share/nginx/html \
-v /usr/local/software/nginx/conf/conf.d:/etc/nginx/conf.d \
-v /usr/local/software/nginx/logs:/var/log/nginx \
-d nginx
配置实现负载均衡
打开nginx.conf
在http中配置
完整的文件内容:
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log notice;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
#myCode:
#配置上有服务器,形成负载
upstream activityBalance{
server 192.168.133.100:15348 weight=1;
server 192.168.200.113:15348 weight=1;
}
server{
keepalive_requests 120; #单连接请求上限次数
listen 8080; #监听端口号
location /api/{
proxy_pass http://activityBalance/api/; #反向代理服务器的访问地址
proxy_set_header Host $host; #主机ip
proxy_set_header X-real-ip $remote_addr; #客户端访问的真实ip
proxy_set_header X-Fowarded-For $proxy_add_x_forwarded_for; #代理转发历史
proxy_redirect off;
}
}
include /etc/nginx/conf.d/*.conf;
}
此时访问nginx会负载均衡到两个服务器
